Electron pair dot structure in the case of ammonia is portrayed by the valence electrons surrounding the N atom. The Lewis point structure for ammonia displays that the nitrogen atom connects 1 pair of electrons with each of the three H atoms, resulting in a complete of a trio connected pairs of electrons. The NH3 molecule adopts a trigonal pyramidal structure due to the arrangement of the outer electrons according to its Electron pair Beverage cup structure. In the Lewis symbol depiction of NH3, the nitrogen atom is enclosed by three points, each representing a pair of united electrons with a hydrogen atom.
